# Get the Latest Package ID

## **getPackageId - NAVI API**

The `getPackageId` API is publicly accessible and retrieves the latest package information for the NAVI Protocol. This endpoint provides the current `packageId` in use, along with a list of outdated package IDs for reference. It helps developers ensure they are working with the most up-to-date package when interacting with NAVI's smart contracts.

## **getPackageId - NAVI SDK**

The `getLatestProtocolPackageId` function in the NAVI SDK retrieves the most recent `packageId` used in the NAVI Protocol. This function is essential for PTB developers to ensure they are interacting with the latest version of NAVI’s smart contracts in their JavaScript-based code.

```javascript
import { getLatestProtocolPackageId } from 'navi-sdk/dist/libs/PoolInfo';

const id = await getLatestProtocolPackageId();
```
